A singer named Magnolia performs frequently in the Third Rail, making it one of the only places in the entire Commonwealth with live entertainment. Also, MacCready, a potential companion, can be found here.
The station is based on the real-world State station. Like its real-world counterpart, the station is also located under the Old State House. However, markings on the wall designate the station as "Scollay Square."
The term "Third Rail" is used by railway workers to call the conductor rail found on electrified railway lines such as those found in subways.
